[0027] See also Figure 1 , a lifting device of a dissolution tester comprises a frame structure and a lifting structure.

[0028] See also Figure 2The frame structure includes a base 1, and a support rod 2 is fixed to each of the four corners on the upper end of the base 1. A hollow rod 3 is fixedly installed in the middle of the left and right sides of the upper end of the base 1. The hollow rod 3 and the upper end of the support rod 2 are fixedly installed with a common bracket 4. The interiors of the support rod 2 and the hollow rod 3 are hollow structures, both of which are made of metal, and the support rod 2 and the hollow rod 3 pass through the bracket 4. The hollow rod 3 and the support rod 2 can make the lifting device only move up and down, and at the same time have the function of maintaining a horizontal state. A number of containers 5 are sleeved on the bracket 4, and a fixer 6 is fixedly installed in the middle of the upper end of the bracket 4. The fixer 6 is a T-shaped structure, and the left and right sides of the fixer 6 are provided with through holes at the upper and lower ends. Hole 1 is circular and has a diameter larger than that of the screw 12. The function of the fixer 6 is to fix the up and down directions of the threaded bevel gear 13 without fixing the rotation direction of the fixer 6, so that it can rotate normally between the hollow rod 3 and the fixer 6, and will not move up and down due to its own rotation. Baffles 7 are fixedly installed on both sides of the upper end of the bracket 4. The function of the baffle 7 is to ensure that the gear on the gear rod 14 is fully engaged with the threaded bevel gear 13 to prevent the lifting device from being unstable due to insufficient cooperation. The baffle 7 is an inverted U-shaped structure with two through holes on the left and right ends. The through hole 2 is circular and has a diameter larger than the diameter of the cylinders at both ends of the gear rod 14. A stirring rod 8 is inserted in the middle of each container 5.

[0029] See also Figure 3-4The lifting structure includes a console 9, and a long rod 10 is fixedly installed at each of the four corners at the bottom of the console 9. The long rod 10 is inserted into the support rod 2. A plurality of clamping plates 11 are fixed at the upper end of the console 9, and the clamping plates 11 are clamped with the stirring rod 8. Screws 12 are fixedly installed in the middle of both sides of the bottom of the console 9. The screw 12 is inserted into the hollow rod 3. A threaded bevel gear 13 is threadedly connected to the middle of the screw 12. A threaded through hole three is provided inside the threaded bevel gear 13. The screw 12 is threadedly connected to the threaded through hole three on the threaded bevel gear 13. Bevel teeth are provided on the side. The threaded bevel gear 13 is clamped between the fixer 6 and the hollow rod 3. A common gear rod 14 is meshed at the rear end of the threaded bevel gear 13. The gear rod 14 is clamped between the two baffles 7. Two gears are arranged on the gear rod 14, and the two ends are cube structures. The helical teeth on the threaded helical gear 13 mesh with the gears on the gear rod 14. The right end of the gear rod 14 is sleeved with a shaft sleeve 15. The function of the shaft sleeve 15 is to connect the motor and the gear rod 14 so that they are tightly connected and work more efficiently during the lifting process. A square groove 1 is provided inside the left side of the shaft sleeve 15, which is clamped by the cube structure on the gear rod 14. The right side of the shaft sleeve 15 is a through hole 4, which is connected to the AC motor. The AC motor can change the direction of rotation during the rotation process to achieve lifting. When the AC motor rotates clockwise, the gear shaft rotates clockwise. Due to the helical teeth meshing, the threaded helical gear 13 rotates counterclockwise in the horizontal plane. Because the threaded helical gear 13 is threadedly connected to the screw rod 12, and the upper and lower ends of the threaded helical gear 13 are clamped, during the rotation of the threaded helical gear 13, the screw rod 12 will move up and down to ensure a stable threaded connection with the threaded helical gear 13, so as to achieve the up and down movement of the console 9 and complete the lifting and lowering of the stirring device of the dissolution tester.

[0030] In summary, the lifting device of the dissolution tester maintains stability during the rising and falling process through the mutual cooperation between the two screws 12, the two threaded bevel gears 13 and the gear rod 14, and the lifting device will not fall due to gravity when the gear rod 14 stops rotating. At the same time, it plays a supporting role, making the lifting device more stable.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
